Commands should expand the wildcards on Windows, the cmd prompt doesn't.
Because of that sancov was not finding the needed file.
To deal with this, we use ls and xargs from gnu win utils.

We need to set BINARY_DIR to: ${CMAKE_BINARY_DIR}/lib/Fuzzer/test , so the dll
is placed in the same directory than the test LLVMFuzzer-DSOTest, and is found
when executing that test.
As we are using CMAKE_CXX_CREATE_SHARED_LIBRARY to link the dll, we can't modify
the output directory for the import library. It will be created in the same
directory than the dll (in BINARY_DIR), no matter which value we set to
LIBRARY_DIR. So, if we set LIBRARY_DIR to a different directory than BINARY_DIR,
when linking LLVMFuzzer-DSOTest, cmake will look for the import library
LLVMFuzzer-DSO1.lib in LIBRARY_DIR, and won't find it, since it was created in
BINARY_DIR. So, for Windows, we need that LIBRARY_DIR and BINARY_DIR are the
same directory.

I add 2 changes to make the tests work on 32 bits and on 64 bits.
I change the size allocated to 0x20000000 and add the flag: -rss_limit_mb=300.
Otherwise the output for 32 bits and 64 bits is different.
For 64 bits the value 0xff000000 doesn't exceed kMaxAllowedMallocSize.
For 32 bits, kMaxAllowedMallocSize is set to 0xc0000000, so the call to
Allocate() will fail earlier printing "WARNING: AddressSanitizer failed to
allocate ..." , and wont't call malloc hooks.
So, we need to consider a size smaller than 2GB (so malloc doesn't fail on
32bits) and greater that the value provided by -rss_limit_mb.
Because of that I use: 0x20000000.

We need to build all the tests with -O0, otherwise optimizations may merge some
basic blocks and the tests will fail.
In this diff, I simplify the cmake implementation and I remove the flags for
Windows too (/O[123s]).

Remove dependency on FileCheck, sancov and not for tests on Windows.
If LLVM_USE_SANITIZER=Address and LLVM_USE_SANITIZE_COVERAGE=YES, this will
trigger the building of dependencies with sanitizer instrumentation.
This will fail in Windows, since cmake will use link.exe for linking and won't
include compiler-rt libraries.

In order to use sanitizers on Windows, we need to link against many runtime
libraries which will depend on the target being created (executable or dll) and
the c runtime library used (MT/MD).
By default, cmake uses link.exe for linking, which fails because we don't
specify the appropiate dependencies. As we don't want to consider all of that
possible situations which depends on the implementation of the compiler-rt, the
simplest option is to change the rules for linking executables and shared
libraries, using the compiler instead of link.exe.
Clang driver will consider the sanitizer flags, and automatically provide the
required libraries to the linker.

I added a new flag RunningCB to know if the Fuzzer's main thread is
running the CB function, instead of using (!CurrentUnitSize).
(!CurrentUnitSize) doesn't work properly. For example, in FuzzerLoop.cpp,
inside ShuffleAndMinimize() function, we execute the callback with an
empty string (size=0). Previous implementation failed to detect timeouts
in that execution.
Also, I add a regression test for that case.
